- Be ithnown that 1, CHARLES EBELING, r citizen of the United States,'residing at JD. Grove, in the county of tlhio and State West Virginia, have invented :1 newond .tul- Drcd er for ll ulverulent Materiel, of uoh the fo llowing is a specification. This invention relates to dredgers for dist sting pulveruleut material, such as powdered 'enamel used in the manufacture of hath tubs and other enameled structures.

@ne of the objects of the present invention.

to provide a vibrator located close to the sieve, of the dredge: and mounted to recipro; ozite along a line intersecting the longitudinal axis of the handle, there being anvils in the path of thevihratcr which are designed to be successively struck by said vibrator which, when reciproceted at high speed strikes the snvils in rapid succession, thus vibrating the sieve to such an extent as to insure uniform discharge of pulverulent Eli " T6 is an enlarged section material irrespective of the manner in which the dredger may he held. Both hands of the operator urethus free to handle the device and the operation of distributing the material can thus he more quickly and accurately curried on than by any of the methods here toidre devised.

With the foregoing and other objects in view which will appear as the description proceedgthe invention resides in the comemotion and arrangement of parts and in the details of construction hereinafter dcscribed and claimed it being understood that changesin the precise embodiment of the invention herein disclosed can he made Within the scope of what is cluimcd Without departing from the spirit. of the invention.

In the .cgicompanying drawings the pre ferred, form of the invention has hcen shown. ln saiddrdi'vings :-.hi;zurc l is a. side elevation ofthe dredgei. l 2 :1 plan view thereof the supporting member being removed. Fig. 3 is a side elevation of u portion' of. the El -edger with the vibrator arranged in a different position relative to the bundle. Fig. d is an enlarged long udinul section through the vibrator and its casing. Fig. 5 is an enlarged section through the controllin valve and adjacent parts. l ig. on the line rip-l Fig. 2. v Referring to the figures by charsctersot reference ignutes a 'oulverulent conom of which is formed of Wire gauze of iine mesh, as indicated at 2 in Fig. This container has a stem 3 engaging an arm at which projects from the casing 5' of the vibrator, there being another arm 6 extending from said casino: and connected to the handle I of the dredger, this handle being either S()l1(l or tubular losing 5 has its ends cioscd by anvil blocks 8 preferably formed of hardened metal and cups 9 are screwed onto the ends of the cosing and constitute ohutments for the anvil blocks. The vibrator 10 is preferably cylindriest 21nd fits-snugly Within the casing 5, this block having reduced end portions 1].

designed to strike the respective anvil blocks. Moreover annular grooves-12 are which i 'otullv coi'uicctcd to it controlling lever 5 wnimct l to the casing" 19 and held normally in p sition with valve 21 closed, by :1 spring 2 Pi nipple 24 projects from 0? end of the passage 20 and o flexible hose is u ispted to he seuiii'cd thereto by a clip or the like.

A yoke may be connected to the handle, this yoke being engaged by a supporting cod 28 extending upwurdly from the dr 'zlger and mounted said cord carrying, at its free end, a counter holunce 30. The said cord is preferably to oed with an elastic portion 31 which a. metal spring, a. rubber cord, or the j the structure shown in Fig. l, the vi- .ncvehle in ii, plane parallel with as preferred.

on guide sheaves 29,

registering with one of the inlet ports 14:, i

the bottom or the container 1 but it is to be understood that said vibrator can be caused to reciprocate in any direction provided its path of movement is along a line intersecting the longitudinal axis ofthchandle 7. For example, and as shown in Fig. 3-, the said vibrator may be so mounted as to reciprocate along a line extending perpendicularly to the plane occupied by the bottom of the container. 1

In using the dredger the same is suspended by the counter-balanced supporting structure, above the object to be enameled and the container 1 is then partly or entirely filled with the pulverulent material. The flexible hose 25 is connected to a reservoir containing air under pressure or to a suitable air forcing means. The operator grasps the handle 7 close to the valve casing 19 and after he has brought the container to proper position, he swings the lever 22 so as to open valve 21. Air immediately passes throu h the valve casing to pipe 16 and thence to t e ports 14. The air first enters one of the grooves 12 in the'vibrator and is then directed through the adjacent end of said vibrator and into the space between the vibrator and one end of the casing, thus shifting the vibrator violently against the anvil block at the other end of the casing. The direction of the air is then promptly reversed so as to drive the vibrator in the opposite direction and a rapid reciprocation of the vibrator is thus set up, said vibrator hitting the anvil blocks violently upon the completion of its successive strokes and this hitting resulting in a practically continuous vibrationor jarring of the container 1. As the line of force extends transversely of the handle, it will be apparent that none of the vibrations will be absorbed by the hand or 7 hands of the operator grasping the handle.

It will be obvious that spring 31 is not' necessary unless the vibrator reciprocates vertically, as in Fig. 3, in which event it is necessary to have a yielding support to permit downward movement of the container and vibrator casing under the impact of thedown strokes of the vibrator.

As soon as the lever 22 is released by the operator, spring 23 shifts it automatically so as to close the valve 21 and thus shut off the supply of air to the vibrator casing. The operation a of the vibrator will promptly cease.

Although air under pressure can be used as a medium for actuating the vibrator, it is to be understood that steam, water-or the 7 like may be employed equally as well and, with some modifications of structure, said vibrator can be operated electrically.

What is claimed is:-

1. A dredger including-a. sitter, a handle extending therefrom, and a vibrator housed within the handle and mounted for move ment across the longitudinal axis of the ban- Q. A dredger includin a sitter, a handle, a vibrator casing upon t e handle, a vibrator mounted to reciprocate within the casing and across the longitudinal axis of the bandle, and separate spaced meansin the path A of the vibrator for receiving successively the impact therefrom upon the completion of the successive movements of the vibrator.

3. -A dredger including a sifter, a handle within the casing, means for controlling the operation of the vibrator, and separate means at opposite sides of the path of the vibrator for receiving the impact therefrom upon the completion of the successive strokes of the vibrator.

5. A dredger including a sifter, a handle, a casing carried by the handle, and power propelled means mounted within the handle for automatically jolting the casing and handle along lines intersecting the longit-u dinal axis of the handle upon the completion of each movementof said means. v

6. A dredger including a sitter, a casing connected theretb, anv1l blocks mounted within the ends of the casing, a vibrator mounted to reciprocate within .the casin and to successively strike the anvils, an means for reciprocating the vibrator, a lon a path intersecting the longitudinalaxis o the handle.

In testimony that I-claim the foregoing as my own, I have hereto afiigted my s gnature in the presence of two witnesses.
